Neuroscience – LBT-3627

Click to read

Longevity Biotech is currently developing LBT-3627 as a novel neuroprotective agent as a possible treatment for disorders such as Parkinson’s Disease. LBT-3627 is a Hybridtide® that targets the VIP family of receptors – specifically the VPAC2 receptor subtype. Empirically, VPAC2 provides more protection than the closely related VPAC1 receptor. Together with the team at the University of Nebraska Medical Center, we have worked to determine the details regarding the protective mechanism along with functional endpoints. The results were recently published and describe a variety of experiments each providing insight into the unique immunomodulatory mechanism of action of LBT-3627. Longevity Biotech is actively progressing this program through preclinical development and towards clinical trials. Our initial focus is on neurodegenerative disorders, including Parkinson’s Disease.

LBT-3627 was specifically designed to be >1000x selective for VPAC2 over the closely related VPAC1. Selectivity was determined using engineered mammalian cell lines with the human receptors, using cyclic AMP (cAMP) as the readout for GPCR activation. LBT-3627 was then further optimized for protease stability resulting in the most selective and most stable VPAC2 agonist available.
